Pierre-Emmanuel Viel	e85bacff7b	Avoid obtaining several identical dimensions between two LSH sub-vectors by choosing orthogonal sub-vectors.	11 years ago
Pierre-Emmanuel Viel	112d63ae96	Add a new method for initializing KMeans centers that leads to better clusters and thus better retrieval when final centers have to be existing keypoints instead of clusters barycenters.	11 years ago
berak	2bb3de5aa0	core/utility.hpp missing in flann/timer.h	11 years ago
Pierre-Emmanuel Viel	d3ac1bc314	When a cluster is empty for KMeans, it's better to give it the point from another cluster j that is the furthest one from center j.	11 years ago
Pierre-Emmanuel Viel	92fc763925	Fix some memory leaks in HierarchicalClusteringIndex	11 years ago
Pierre-Emmanuel Viel	0d19685f95	Move templates in dist.h in order to share them between KMeansIndex and HierarchicalClusteringIndex classes.	11 years ago
Pierre-Emmanuel Viel	fa749de0dc	As some processed distances are already ^2, use template to select whether or not we have to ^2 in KMeanspp	11 years ago
Pierre-Emmanuel Viel	5aeeaa6fce	Apply to KMeansIndex KMeanspp the same modification as in HierarchicalClusteringIndex	11 years ago
Pierre-Emmanuel Viel	45e0e5f8e9	Pick centers in KMeans++ with a probability proportional to their distance^2, instead of simple distance, to previous centers	11 years ago
Roman Donchenko	58da54cb7a	Cherry-picked mariusmuja/flann@8c8b0e0cb879666797ab2ac51b9ee438bf84a183. Original author: me.	11 years ago
Roman Donchenko	4c19e0273a	Cherry-picked mariusmuja/flann@b615f2694723fe402b8bbe50d77e622beff7f171. Original author: Alex Wilson.	11 years ago
Roman Donchenko	78c4ffec99	Revert "Fixed a bug in FLANN resulting in uninitialized accesses." This reverts commit `a9975b144a`, to prepare for cherry-picking upstream's solution.	11 years ago
Roman Donchenko	fec697b390	Silenced a few -Wcast-align warnings in the headers. We don't use -Wcast-align ourselves, but the headers trigger warnings for those users who do, which is not nice.	11 years ago
Roman Donchenko	a9975b144a	Fixed a bug in FLANN resulting in uninitialized accesses. This is fixed upstream in mariusmuja/flann@b615f26, but that fix would break binary compatibility, so I had to make a different one. Since the bug isn't quite obvious, here's an explanation. In the const version of any::cast, if policy is a small_any_policy, its get_value returns its input argument. So r becomes a pointer to obj, and the return value is a reference to a local variable, which is invalidated when the function exits.	11 years ago
Roman Donchenko	9ed475cf52	War on Whitespace, master edition: file endings.	11 years ago
Roman Donchenko	e9a28f66ee	Normalized file endings.	11 years ago
Roman Donchenko	f55740da70	Deleted all trailing whitespace.	11 years ago
Roman Donchenko	d9f71b762f	Deleted almost all of the precomp.cpp files. Looks like we don't actually use them; when creating precompiled headers with Visual C++, a dummy .cpp is created at build time.	11 years ago
Alexander Smorkalov	2243118fc0	NEON instruction set enabled for WIN32 on ARM by default.	11 years ago
Roman Donchenko	ac39bfb4cc	Remove HAVE_CVCONFIG_H - it's always defined.	12 years ago

Andrey Kamaev	a3b1971977	Bring back escaped virtual destructors from 2.4.2	12 years ago
Vadim Pisarevsky	d72cc06b96	fixed possibly inccorrect interval measurements in flann's timer (bug #1165 ). Note: this may break binary compatibility, but since the class is not wrapped in Java and not exposed in Windows API, for example (it's considered internal-use class for flann), the effect should be minimal	12 years ago
Andrey Kamaev	56b27bcc7e	Fix inconsistent argument type in HammingLUT distance (flann) this fixes 64-bit MSVC warning	12 years ago
Vadim Pisarevsky	d54f4e1cfb	added #undef True/False to avoid collision with X11 (Patch #1562 )	12 years ago
